  • Fig. 19 is a flow chart illustrating the details of processing of a preset patrol.
  • step S19003 a repeating process of a preset patrol starts in step S19003.
  • the preset display processor 118 calculates the preset position at the current time by the above-mentioned equations in step S19004. Then, the preset display processor 118 sends the calculated preset position and a display request of preset information through the controller 123 to the camera control device 200 in step S19005.
  • the communication controller 211 of the camera control device 200 receives the preset position and the display request in step S19006, and transfers the preset position and the display request to the preset display processor 216 in step S19007. Then, the preset display processor 216 transfers the preset position to the panhead controller 220 in step S19008. After that, the panhead controller 220 adjusts the preset position of the panhead 400 in accordance with the preset position information, and after the adjustment is completed, notifies the preset display processor 216 of the completion in step S19009. Then, the preset display processor 216 makes a request to the image input unit 219 for image data captured by the camera 300 in step S19010.
  • the image input unit 219 acquires the captured image data from the camera 300, and transfers the image data to the preset display processor 216 in step S19011. Then, the preset display processor 216 sends the image data through the communication controller 211 to the monitoring apparatus 100 in step S19012.
  • the communication controller 123 of the monitoring apparatus 100 receives the image data in step S19013, and transfers the image data to the preset display processor 118 (S19014). Then, the preset display processor 118 transfers the image data to the monitoring screen display unit 111 in step S19015. After that, the monitoring screen display unit 111 displays the image data on the monitor 600 in step S19016. Then, processing from step S19004 to step S19016 are repeated until the patrol ends.
  • preset information is generated similar to the preset information generating process in the first embodiment.
  • user types are registered in the fourth embodiment.
  • two kinds of users that is, administrator users and ordinary users
  • the administrator users can see information about both "Administrator” and “Ordinary user”, while the ordinary users can see only information about “Ordinary user” and cannot see information about "Administrator”.
  • the content of the preset information table 242 is as shown in Fig. 20 .
  • the preset information acquisition receiving unit 117 receives user information together with a request for displaying preset information in step S5001 of the preset information acquiring process as shown in Fig. 5 .
  • the preset information acquisition receiving unit 117 requests the camera control device 200 to send the preset information, and sends the user information.
  • the preset information input/output unit 215 compares the content of the preset information table 242 with the user information received from the monitoring apparatus 100, and returns only the preset information that matches the user information, to the preset information acquisition unit 213 in step S5006. That is, the preset information input/output unit 215 selects the preset information to be returned to the preset information acquisition unit 213.
  • Fig. 21A illustrates a display example of a preset list when an administrator user performs operations
  • Fig. 21B illustrates a display example of a preset list when an ordinary user performs operations.
  • the display of a preset list is switched depending on the registered user information according to the present embodiment, the display of a preset list can also be switched depending on the time period.
  • An embodiment of the invention can be realized, for example, by a computer executing a program.
